Hello,
I created my own treeviewer based upon Tom Schindl's article (http://www.eclipse.org/resources/resource.php?id=511).
So my plug-in looks like there is a tree viewer on the left hand side and when I click on an element (my metamodel is different from the one in the article), the details will appear on the right hand side. I would like to group some elements, for example I click on elements (ctrl+mouse) then the selected elements should appear in e.g. table if the user clicked on the Group button. I only have the basic code (treeview + element description) and I just started using JFace so it is quite difficult for me to figure out how a simple thing should be implemented. I would like to know how I should put the selected elements (mostly those elements which are contained in the top-level metaclass - these elements appear in the tree) on the left hand side (project explorer part) into a table which is found on the right hand side (project form area part). Actually, I do not even know what classes/methods should be used to access the list of selected elements from another class.
Thanks and best regards,
John S

Hello,
Actually I have two Parts: ProjectExplorerPart (it has TreeViewer viewer) and ProjectFormAreaPart (it has Button button, Table table).
So when I click on the button I want to start eg. an viewer.addSelectionChangedListener (not sure I need this listener to get the current selected elements, or there is another way, treecontentprovider???). They are in two different classes.
I can listen the selection in the ProjectExplorerPart where there is the treeview, it continously listen and I can monitor it through the consol (println). BUT I should do it in the other ProjectFormAreaPart class, so i could put the selected entries into a table (only see the CURRENT selected elements in the treeview, when I click the button).
In the ProjectFormAreaPart class (Treeview is public in the other class, so I can access that):
button.addSelectionListener(new SelectionAdapter()
{
@Override
public void widgetSelected(SelectionEvent e)
{
TreeViewer tviewer = projectExplorer.viewer;
IStructuredSelection s = (IStructuredSelection) tviewer.getSelection();
System.out.println((IStructuredSelection)tviewer.getSelectio n());
...
When I click on the button, nothing happens, so there is something wrong with it, perhaps its not the proper way to do it, but I need something similar.
Best Regards,
John

Hello,
Problem is solved with parameter (that is, Treeviewer) passing:
In the changeEditorView class:
public void run() {
projectExplorer = new ProjectExplorerPart(getViewSite(),
sashForm, toolkit, (ChangeModel)resource.getContents().get(0), defaultMgr);
projectDataForm = new ProjectFormAreaPart(getViewSite(),
sashForm, toolkit, editingDomain, resource, defaultMgr,
projectExplorer.getProjectObservable(),projectExplorer.viewe r);
}
Regards,
John
